We will now add dedicated modulation sources (another LFO and Envelope) to control the filter, thus releasing the originals and giving an enormous number of potential combinations. We also add an oscilloscope for viewing the waveforms being output. You can learn a lot from this, so start by viewing the simplest possible waveforms, gradually adding various modulations.

One of the most fun things is to use your hardware to control Reaktor so that it feels as if you are working a “proper” hardware synth. You will need a control surface or keyboard with at least one MIDI CC fader/knob. If you have more, you are really sorted! We will also add a custom knob to apply vibrato to both oscillators simultaniously from a single mod wheel.

Next, we will now add a step sequencer which will modulate cut-off
frequency with user defined steps, in time with your track. NB this is
now beyond the minimum requirement for MT1’s Assignment 4- it just might be
fun though, and there is no reason not to implement it in that work!
